      <h1>Upcoming Events</h1>

      <article>
        <p>03 Oct 2014</p>

<p>We are happy to announce several upcoming Flink events both in Europe and the US. Starting with a <strong>Flink hackathon in Stockholm</strong> (Oct 8-9) and a talk about Flink at the <strong>Stockholm Hadoop User Group</strong> (Oct 8). This is followed by the very first <strong>Flink Meetup in Berlin</strong> (Oct 15). In the US, there will be two Flink Meetup talks: the first one at the <strong>Pasadena Big Data User Group</strong> (Oct 29) and the second one at <strong>Silicon Valley Hands On Programming Events</strong> (Nov 4).</p>

<p>We are looking forward to seeing you at any of these events. The following is an overview of each event and links to the respective Meetup pages.</p>

<h3 id="flink-hackathon-stockholm-oct-8-9">Flink Hackathon, Stockholm (Oct 8-9)</h3>

<ul>
  <li>
    <p>Sample streaming applications (e.g. continuous heavy hitters and topics
on the twitter stream)</p>
  </li>
  <li>
    <p>Implement a simple SQL to Streaming program parser. Possibly using
Apache Calcite (http://optiq.incubator.apache.org/)</p>
  </li>
  <li>
    <p>Implement different windowing methods (count-based, time-based, …)</p>
  </li>
  <li>
    <p>Implement different windowed operations (windowed-stream-join,
windowed-stream-co-group)</p>
  </li>
  <li>
    <p>Streaming state, and interaction with other programs (that access state
of a stream program)</p>
  </li>
</ul>

<h5 id="graph-analysis">Graph Analysis</h5>

<ul>
  <li>
    <p>Prototype a Graph DSL (simple graph building, filters, graph
properties, some algorithms)</p>
  </li>
  <li>
    <p>Prototype abstractions different Graph processing paradigms
(vertex-centric, partition-centric).</p>
  </li>
  <li>
    <p>Generalize the delta iterations, allow flexible state access.</p>
